Putting the "processor" in an external box takes more than a board or two out of the box. it also allows extra realestate to add more and more processing to control other aspects of the display. it allows greater lamp, iris, etc control. so thinking that it would be available as the Lumis np (no processor ) is a false hope. it would not be the same machine by any stretch. more likely to hope for is to possibly get sim to offer the processor (image processing part) as a line item for use in other applications.

but just because the processor is in another box does not mean that they could sell the lumis for less money and still have the same image.

Well, if that is the case, they need to change the specs in their brochure, so people are not buying one for bigger screens. My Lumis has gone back for a few reasons, I will post as soon as it returns.

Wow, 1200 lumens best case for me would be a disaster with the throw and size screen I'm painting. I would reckon I'd be somewhere around 800 lumens with a 30% reduction for my throw with a new bulb. That's with iris open and high bulb! With a further 30% reduction for bulb wear, we're looking at 560 lumens. Would hate to use stretch for 2.37 ratio at this light output level. Also, if we turned the iris on for best contrast, where would those numbers fall? We just measured an RS20 and it had 700 lumens, exactly what the C3X 1080 we were looking at had, so this projector loses a lot of it's advantage on the larger screens if this is what they're coming in at.

It seems to me like someone at the company should be at least letting their dealers and/or customers know what is happening, or this could turn into Mark Zuckerberg part trois.

"If full black fields have the same luminosity on both projectors it follows that the On-Off of the Lumis is in the 60000-150000:1 range (Lumis white is 3 times brighter than RS20, and a RS20 measures easily between 20000:1 and 50000:1). It also means for black a whopping factor of 18 to 30 is used if native On-Off is 5000:1 as reported. Is all of this the case?"

These numbers correspond with subjective impressions being reported, but they far exceed spec's.

It's truly a mystery how this pj does what it does.

"It is really uncanny how the dynamic black works. Because it is a frame by frame analysis, and source dependent, the better the source, the deeper the blacks get."

How does it react when a very dark scene with no bright areas suddenly gets a small but very bright feature?

You really measured a C3X1080 at 700 lumens? Was the unit defective or were you using it at the end of its zoom range/min bulb/iris on?

It is interesting that we measured the same Lumens, which would lead one to believe that this is not a random error, but a planned modification.

If the specs are to be modified in this way, I would certainly expect a refund, as it is not the projector I ordered.

Were you and Wolfgang in the same locale, one could figure on it being a particular geographic's shipment having issues, but it looks like that ain't the case.

I have major trouble believing that Sim would do this on purpose, I mean they would surely realize the negative effect, especially on those people who were so blown away by the performance of the first Lumis models?

Optimistically, I would say that the projectors are throttled back because of a firmware glitch, rather than a deliberate mod.

Well, given the tendency of people to think the worst, Sim2 should make some sort of statement through any channel to ease customer's concerns and avoid a PR disaster especially when the groupthink is that perhaps they are dumbing down the unit intentionally.
